FIELD OF THE DISCLOSURE
[0001] The present disclosure relates to a work machine for baling crop, and more particularly
to a system and method of marking and identifying baled crop.
BACKGROUND
[0002] Hay and foraging equipment are utilized in the processing of plant material and include
mowers, conditioners, flail choppers, windrowers, and balers for both dry and silage
uses. The hay system, such as a square baler, includes a pickup mechanism, which picks
crop material from the ground and supplies it to a bale-forming chamber. The bale-forming
chamber receives the crop material and includes a plunger or piston that applies an
axial force against an accumulation of the crop material to form a substantially square-shaped
bale. The plunger or piston can further apply a force to a face of the bale to further
densify the bale. Once the bale reaches a certain or desired density, the bale may
be pushed and extruded out the rear of the baler.
SUMMARY
[0003] In one embodiment of this disclosure, a communication system is provided for tracking
information related to a baled crop formed during a baling process by a harvesting
machine. The system includes a control unit for controlling the harvesting machine;
a sensing unit mounted to the harvesting machine for detecting a characteristic of
the baled crop; a bale tag coupled to the baled crop, the bale tag including a bale
tag identifier; a bale tag reader for reading the bale tag identifier on the bale
tag; an electronic storage unit disposed in electrical communication with the control
unit; a wireless communication network electrically coupling the control unit, the
sensing unit, the bale tag reader, and the electronic storage unit to one another;
wherein, during the baling process, the control unit assigns a unique bale identifier
to each baled crop, and receives a characteristic detected by the sensing unit and
the bale tag identifier from the bale tag reader via the wireless communication network;
further wherein, the control unit communicates the bale identifier, characteristic,
and bale tag identifier to the storage unit via the wireless communication network.
[0004] In one example of this embodiment, the electronic storage unit comprises a data server
located on the harvesting machine. In a second example, the electronic storage unit
comprises a data server located remotely from the harvesting machine. In a third example,
the electronic storage unit comprises a memory of the control unit. In a fourth example,
the system may include a mobile computing device remotely located from the harvesting
machine, the mobile computing device being in electrical communication with the electronic
storage device via the wireless communication network to access the characteristic,
bale identifier and bale tag identifier. In a fifth example, the system may include
a data matrix stored in the electronic storage unit, the data matrix including a plurality
of columns and a plurality of rows; wherein, for each baled crop, the characteristic,
bale identifier and bale tag identifier of said baled crop is recorded in one of the
plurality of rows or columns of the data matrix. In a further example, the system
may include a second bale tag coupled to the baled crop, the second bale tag including
a second bale tag identifier coupled thereto, wherein the bale tag reader communicates
the second bale tag identifier to the control unit, and the control unit associates
the first bale tag identifier and the second bale tag identifier with the characteristic
and bale identifier. Moreover, the system may include a carrier material fastened
to the baled crop during the baling process, the carrier material including a carrier
material identifier; wherein, the carrier material identifier is communicated to the
control unit and associated with the bale identifier, bale tag identifier, and characteristic
of the baled crop.
[0005] In yet a further embodiment of the present disclosure, a communication system is
provided for storing information related to a baled crop formed during a baling process
by a harvesting machine. The system includes a control unit for controlling the harvesting
machine; a plurality of sensors mounted to the harvesting machine for detecting a
plurality of characteristics of the baled crop; a carrier material fastened to the
baled crop during the baling process, the carrier material including a carrier material
identifier; a bale tag coupled to the carrier material, the bale tag including a bale
tag identifier; a bale tag reader for reading the bale tag identifier on the bale
tag; an electronic storage unit disposed in electrical communication with the control
unit; a wireless communication network electrically coupling the control unit, the
plurality of sensors, the bale tag reader, and the electronic storage unit to one
another; wherein, during the baling process, the control unit assigns a unique bale
identifier to the baled crop, and receives the plurality of characteristics detected
by the plurality of sensors and the bale tag identifier from the bale tag reader via
the wireless communication network; wherein, the control unit communicates the bale
identifier, the plurality of characteristics, and bale tag identifier to the storage
unit via the wireless communication network; further wherein, the wireless communication
network is adapted to electrically couple a mobile computing device to the electronic
storage unit to allow access from a remote location to the bale identifier, the plurality
of characteristics, and bale tag identifier.
[0006] In yet another embodiment, the present disclosure provides a method for monitoring
properties of organic material to be stored in the absence of air in a bale wrapped
with film, to a bale composed of organic material to be stored in the absence of air
and wrapped in a bale, to an arrangement for pressing organic material into a bale
or for wrapping organic material to be stored in the absence of air that has been
pressed into a bale with wrapping film, to a combination of such an arrangement and
a reading device for reading out sensor data, as well as to a reading device for sensor
data from a sensor assembly that is in contact with organic material to be stored
in the absence of air that has been pressed into a film-wrapped bale, wherein the
sensor assembly is equipped with a sensor for detecting properties of the material
and an electronic transmitting device connected to the sensor for transmitting sensor
data, and the reading device comprises a receiving device for receiving the sensor
data, a processor for processing sensor data, a memory and a display device for displaying
the processed sensor data.
[0007] In order to monitor properties of organic material to be stored in the absence of
air in a bale wrapped with film, a sensor assembly may include a sensor for detecting
properties of the material and an electromagnetic transmitting device connected to
the sensor in order to transmit sensor data to a reading device. The sensor may be
brought into contact with the material before wrapping the bale with film or while
wrapping the bale with film. In other words, a sensor assembly, equipped with a sensor
for detecting properties of the material and an electromagnetic transmitting device
connected to the sensor in order to transmit sensor data to a reading device, is brought
into contact with the material of the bale. The sensor assembly can thus be inserted
into the material forming the bale before the bale is pressed, or after pressing,
or can be mounted on the surface thereof.
[0008] Alternatively, a wrapping material (film, twine or netting) may be secured in a manner
such that it is possible for the sensor assembly to ultimately come into contact with
the material of the bale. This can be done onboard a baler or when the bale is lying
on the field before wrapping, e.g., by hand or by means of a suitable device, or on
a baler before wrapping or while wrapping the bale with a plastic film. Subsequently,
the sensor of the sensor assembly is in contact with material of the bale that is
wrapped with a film. The sensor data can be read out with a reading device and the
bale status detected by the sensor can be captured without having to puncture the
film and thus destroy the exclusion of air.
[0009] In a further embodiment, the sensor assembly is fixed to the side of the film facing
the bale and then the film is wrapped along with the sensor assembly around the bale.
The sensor assembly may be withdrawn from a supply onboard the baler and applied (e.g.
laminated or glued) to the film that will then be wrapped around the bale. Alternatively,
a supply of film can be provided with a plurality of sensor assemblies by the manufacturer
and sections thereof that each contain one or more sensor assemblies can be wrapped
around the bale.
[0010] On the side of the film furnished with the sensor assemblies, the supply of film
can be provided with markings that facilitate finding the sensor assembly. An operator
can thus orient the reading device to the sensor assembly or, if a short-range electromagnetic
transmission technology such as near field communication or RFID technology is used
between the sending device of the sensor assembly and the reading device, can bring
the reading device near the sensor assembly in order to ensure that the data of a
respective desired bale is displayed. It is also conceivable, however, to read out
a plurality of sensor assemblies simultaneously with the reading device and to indicate
to the operator which data belongs to a respective bale, which can be done by displaying
a direction identification (arrow) or an image of the inspected bale captured by the
camera and associating the read data with the bales on the display device of the reading
device in the manner of virtual reality.
[0011] In addition, the supply of film can be furnished on the side facing away from the
bale with a machine-readable identification that can be used to control an arrangement
for wrapping the bale. The arrangement for wrapping the bale can thus detect how much
film remains in the supply or can ensure that, after a finished wrapping process,
the film is cut off at the correct time before another sensor assembly is wound onto
the bale. Since the film may be stretched while wrapping the bale, the printed identification
may be compressed in such a manner that it is machine-readable after stretching.
[0012] The reading device for transmitting the sensor data from the sensor assembly that
has been written to the sensor assembly may include a receiving device for receiving
the sensor data, a processor for processing the sensor data, a memory and a display
device for displaying the processed sensor data. In particular, the processor can
be operated so as to calculate and display properties of the bale, particularly in
the core zone of the bale, based on a physical model loaded into the memory and based
on the sensor data. For calculating the properties of the bale by means of a captured
identification of the bale (e.g., on the basis of a storage device of the sensor assembly
or a camera or scanner of the reading device and unique for each bale), the processor
can retrieve additional data for the present bale from the memory or from a memory
device of the sensor assembly or from a remote server. This may be done, for example,
in order to calculate a critical pH value based on the content of dry matter during
the pressing process and compare the pH value to a pH value captured by sensors or
include the time between the pressing process and the wrapping process in the model
calculation.
[0013] In another embodiment of this disclosure, a method is provided of storing information
corresponding to a baled crop during a baling process. The method includes providing
a harvesting machine including a control unit, a sensor, and a bale tag reader; forming
the baled crop with a bale tag by the harvesting machine; identifying the baled crop
by the control unit with a bale identifier; sensing a characteristic of the baled
crop by the sensor; detecting a bale tag identifier associated with the bale tag by
the bale tag reader; communicating the characteristic and bale tag identifier to the
control unit; corresponding the characteristic, bale tag identifier and bale identifier
of the baled crop to one another; and storing the characteristic, bale tag identifier
and bale identifier in an electronic storage unit that is in electrical communication
with the control unit.
[0014] The method may include communicating the characteristic, bale tag identifier and
bale identifier to a remote location via a cloud-based network. In one example, the
storing step includes storing the characteristic, bale tag identifier and bale identifier
in a data server located on the harvesting machine. In a second example, the storing
step may include storing the characteristic, bale tag identifier and bale identifier
in a data server located remotely from the harvesting machine. Moreover, the method
may include storing the characteristic, bale tag identifier and bale identifier in
a data matrix, the data matrix including a plurality of columns for the characteristic,
bale tag identifier and bale identifier. In addition, the forming step may include
forming the baled crop with two or more bale tags coupled thereto, each of the two
or more bale tags including a bale tag identifier unique to the respective bale tag;
wherein, the plurality of columns in the data matrix includes a column for each bale
tag identifier for the baled crop. In a further example, the forming step includes
forming a plurality of baled crops with the harvesting machine, each of the plurality
of baled crops including at least one bale tag coupled thereto, and each of the at
least one bale tag including a bale tag identifier unique to the respective bale tag;
and identifying each of the baled crops by the control unit with a bale identifier;
wherein, the data matrix includes a plurality of rows, and the bale identifier of
each of the plurality of baled crops being stored in one of the plurality of columns
and the plurality of rows.
[0015] In this embodiment, the method may include electrically coupling the storage unit
to a mobile device over a wireless network; and permitting access over the wireless
network to the stored characteristic, bale tag identifier and bale identifier via
the mobile device. In another example, the sensing step may include sensing at least
one of a moisture content, bale size, bale location, and nutritional value of the
baled crop. Moreover, the detecting step may include scanning a barcode, quick response
code, or RFID chip on the bale tag. The method may further include detecting information
related to a carrier material; wrapping the baled crop with the carrier material during
the baling process; communicating the information related to the carrier material
to the control unit; associating the information related to the carrier material with
the characteristic, bale tag identifier and bale identifier; and storing the information
related to the carrier material in the storage unit.

DETAILED DISCLOSURE
[0017] The embodiments of the present disclosure described below are not intended to be
exhaustive or to limit the disclosure to the precise forms disclosed in the following
detailed description. Rather, the embodiments are chosen and described so that others
skilled in the art may appreciate and understand the principles and practices of the
present disclosure.
[0018] A baled crop may be formed in a square or round baler and composed of organic material
such as silage or hay. The baled crop may be desirably stored in the absence of air.
For this purpose, it is conventional to use a so-called bale wrapper that is mounted
together with a square or round baler on a common chassis or which picks up a bale
along with netting or twine from the field as a separate machine and wraps it with
film. Due to wrapping the baled crop with film, a farmer cannot monitor the quality
of the bale without destroying the film. For assessing the storage life, usability
and value of the baled crop during storage, a sensor-based quality assessment may
be used to monitor the quality of the crop. An end user, such as a farmer, may be
interested in different quality information about a given crop. For example, if the
silage formation process is incomplete or atmospheric oxygen enters (due to damage
to the film) there is potential risk of post-heating or hot fermentation in which
the bale warms up and the proteins are damaged. Moreover, at pH values above a critical
pH value (typically a pH value of approximately 4.5) microbes harmful to health can
arise. The content of dry matter may influence the critical pH value (with increasing
dry matter content, the critical pH value increases). Also, tightly pressed bales
may yield a higher silage quality.
[0019] In view of this, attaching electronic identification means on which data characterizing
the bale, such as moisture, place of origin, etc., can be stored in or on a bale.
Alternatively, the data or information may be stored on the baler for purposes of
precision agriculture or in order to be able to locate the bale subsequently. In many
applications, however, subsequent changes of the properties of the baled crop cannot
be detected by these conventional procedures. In this disclosure, different systems
and methods provide alternative means for identifying and tracking data or information
about a baled crop.
[0020] Referring to Fig. 1, a plan view of a combination 12 of a baler 16 and a bale wrapper
10 is shown. The baler 16 may be a square baler, a round baler, or harvesting machine
used as an arrangement for pressing organic material into a bale. The bale wrapper
may be used as an arrangement for wrapping organic material pressed into a bale with
a film for airtight storage. The combination 12 is constructed on a frame 14 that
is supported on the ground by wheels or other known ground-engaging mechanisms 15.
The baler 16 includes a rear door 18.
[0021] The combination 12 is towed in operation via a drawbar 20 behind a traction vehicle
(not shown) such as a tractor or other work machine. In an alternative embodiment,
a baler 16 and a separate bale wrapper that are towed by associated traction vehicles
across a field may be used for carrying out the principles and teachings of this disclosure.
Moreover, the combination 12, or the baler 16 or bale wrapper 10, may also be self-propelled.
[0022] A bale 22 produced in the baler 16 is brought by a movable table 24 from the baler
16 into a wrapping position in the bale wrapper 10. During the wrapping operation,
the bale 22' to be wrapped is therefore on the table 24, which includes a belt 26
that rolls about two rollers 28. Above the table 24 are two diametrically opposed
arms 30 with vertical and horizontal portions perpendicular to one another that rotate
around the bale 22'. Each vertical portion of the arms 30 holds a film dispenser 32.
The central ends of the horizontal portions of the arms 30 are connected to a drive
arrangement 34 designed to rotate the arms 30 about a central vertical axis. The drive
arrangement 34 is connected by a carrier frame 38 to the frame 14 and includes a hydraulic
motor connected to the hydraulic system of the traction vehicle. During the wrapping
operation, the drive arrangement 34 or a separate hydraulic motor also drives the
rollers 28 so that the bale 22' rotates about its horizontal axis while the arms 30
rotate about the bale 22' and film is unwound from the film dispensers 32 and wrapped
around the bale 22'. Film holders 36 press the film during the start of the wrapping
operations against the bale 22' and cut the film after wrapping. The speeds of the
arms 30 and the rollers 28 can be synchronized in order to achieve a desired positioning
of the film on the bale 22'.
[0023] Referring now to Fig. 2, a reel 40 of film 56 is shown mounted on one (or both) of
the film dispensers 32 in order to wrap the bale. The film 56 includes a carrier material
48, on which sensor assemblies 42 having a sensor 46 for detecting properties of the
material in the bale and an electromagnetic transmitting device 44 connected to the
sensor 46 in order to transmit the sensor data are applied during manufacturing with
a defined spacing to the inner side of the film (i.e. on the side coming into contact
with the bale 22'). The sensor assemblies 42 can, in particular, be RFID chips, which
are also available with integrated sensors 46.
[0024] On the opposite side of the carrier material 48, visible markings 50, which facilitate
finding the sensor assemblies 46, are printed during manufacturing on the film 56
at locations where sensor assemblies 42 are mounted on the inner side. On the basis
of the marking 50, a short range reading device 54 (Fig. 4) can be brought into the
vicinity of the sensor assembly 42 to read the data from the sensor assembly 42. In
addition, machine-readable identifiers 52, which contain information regarding the
film 56 that can be used for controlling the bale wrapper 10, for example, are applied
to the outer side of the carrier material 48. These visual identifiers 52 can be designed
to be machine-readable in the form of a one-dimensional or two-dimensional bar code
(linear bar code, quick response (QR) code, etc.). The sensor assemblies 42 may be
applied to the outer side of the carrier material 48, and the identifiers 52 and markings
50 to the inner side, particularly if the outer side of the carrier material 48 were
to come into contact with the bale 22'.
[0025] Stretchable film 56, which is pre-stretched during application to the bale 22, may
be used for wrapping bales 22 composed of silage and haylage. This pre-stretching
may be between 50% to 70%. The electronic sensor assemblies 42 applied to the film
56 are integrated in stretchable film 56 in such a manner that they do not change
to a particular extent during elongation of the film 56 in the longitudinal direction
of the film structure and also are not damaged. It is also necessary to take care
during application or printing of the machine-readable identifiers 52 on the stretchable
film 56 so that they are readable both before and after stretching of the film 56.
A compression of the identifiers 52 in the unstretched state may therefore be necessary.
[0026] In Fig. 3, a bale 22 is shown that has been wrapped with film 56. A sensor assembly
42, and in particular the sensor 46, is situated in contact with the surface of the
material of the bale 22 and is on the side of the film 56 that faces the bale 22.
The sensor 46 can detect properties of the material of the bale 22, e.g., temperature,
moisture content, pressure or conductivity, and transmit corresponding signals to
the transmitting device 44.
[0027] The reading device 54, as shown in Fig. 4, may include a receiving device 60 for
receiving sensor data transmitted by the transmitting device 44 of the sensor 46,
a processor 62 for processing the sensor data, a memory 64, and a display device 66
for displaying the processed sensor data. The device 54 enables the display of sensor
data on the display device 66, directly or after further processing. If necessary,
the reading device 54 (designed in particular as a handheld device such as a smart
phone, tablet computer or laptop) can query additional data via a transmission device
56 and an antenna 58 from a server 72, which communicates via an associated transmitting
device and an antenna 70 with the transmitting device 56 via any desired protocol
(e.g., a protocol for wireless telephony or an Internet protocol) and is located at
a remote location 68. The power for the transmitting device 44 and, if necessary,
the sensor 46 of the sensor assembly 42 can be supplied wirelessly via the reading
device 54.
[0028] The sensor 46 measures parameters such as temperature, moisture content, pressure
and conductivity of the crop material in the peripheral zone 74 of the bale 22. This
information is read via the receiving device 60 of the reading device 54 and transferred
to the processor 62. The reading device 54 is equipped with a display device 66 for
displaying the relevant quality and storage parameters of the bale 22. The processor
62 is programmed, based on a physical model previously loaded into the memory 64 (as
a program, a table, a database or the like) and, based on the data from the sensor
46, to determine or make calculations regarding the bale properties (e.g., in the
core zone 76 of the bale 22). For these calculations, additional data for the bale
22 can be retrieved from the memory 64 or the server 72 by means of identification
data for the bale 22, which can be stored in a memory of the sensor assembly 42. This
data can be stored directly in the memory of the sensor assembly 42.
[0029] In one example, the content of dry matter during the pressing process may be detected
and stored since it defines the critical pH value. By means of the sensor 46 (e.g.
based on a measurement of the electrical conductivity), the current pH value can thus
be determined and compared to the critical pH value. For grass silage, the time between
the pressing process and the wrapping process may influence the silage quality. In
at least one aspect, the desired time is less than two hours. This information, for
example, can also be included in the model calculation.
[0030] Alongside the values detected directly by the sensor 46, it is also possible by means
of the described calculation based on the model to calculate and display the corresponding
values in the core zone 76, as well as the current pH value, the critical pH value,
the content of dry matter, an appropriate consumption date or pressing density. Information
regarding the status of the bale (i.e. whether or not it can still be used) can also
be determined, and a warning can be issued in the event of hot fermentation. This
data can be transmitted by the reading device 54 to the server 72 so that the owner
of the bales 22 can retrieve the appropriate information there.
[0031] Referring to Figs. 6 and 7, two additional possible embodiments are shown for applying
the film 56 to the bale 22. While the carrier material 48 in the embodiment shown
in Fig. 3 covers the outer surface of the cylindrical bale 22 (i.e. the film 56 is
not wound around the bale 22 by the bale wrapper 10, but rather by the baler 16 of
Fig. 1), the bale 22 is wrapped according to Figs. 6 and 7 alternately perpendicular
and parallel to the axis of the cylinder for which the bale wrapper 10 of Fig. 1 is
used. The sensor assembly 42 is also or exclusively applied laterally to the bale
22, i.e., on the end face thereof.
[0032] Fig. 6 additionally illustrates the film 56 enveloping the bale 22 and consists of
different areas with different material properties. Thus, under certain circumstances
it may be desirable to use a less elastic material 78 as the carrier material 48 for
applying the sensor assemblies 42, and to use a more stretchable material 80, connected
to the material 78, for the actual enveloping of the bale 22.
[0033] In the embodiment of Fig. 7, the wrapped bales 22 may be wound with 4 to 8 plies.
It is therefore possible to use two different materials 78, 80 for the film 56. One
difficulty that arises from the use of two different materials 78, 80 (on one reel
40) for winding the bale 22 is that the material length for a bale 22 is defined by
the reel 40 composed of alternating inelastic carrier material 78 and stretchable
stretch film 80 that is inserted into the bale wrapper 10. The machine-readable identifiers
52 and a corresponding reading device on the bale wrapper 10 can be used to detect
the type or running length of the film 56, in order to actuate the drive arrangement
34 and the film holders 36 appropriately and ensure that each bale 22 is wound with
at least one sensor assembly 42.
[0034] If sensor assemblies 42 end up in outer layers of the film 56, for example, because
the carrier material 48 is uniformly and continuously equipped with sensor assemblies
42, it is expedient if the sensor assemblies 42 detect whether they are located between
two layers of the carrier material 48 and therefore have no direct contact with the
crop material. In such cases, the data from the affected sensor assemblies 42 may
not be evaluated. Such an arrangement may be desirable if the unit costs for the sensor
assemblies 42 is low. For a carrier material 48 equipped with numerous sensor assemblies
42, it may be advantageous to arrange the sensor assemblies 42 at the edge of the
carrier material 48, as shown in Fig. 8, because there is a higher degree of overlapping
in the central area of the carrier material 48.
[0035] Referring now to Figs. 9-12, a further aspect of the present disclosure is disclosed.
In Fig. 9A, large square baler 912 may be towed across a field by agricultural vehicle
910. (It will be understood that various other configurations are also possible, For
example, the disclosed sensor assembly and method may be utilized with a variety of
balers or other equipment.) Baler 912 may include housing 914, which may generally
shield various internal components of baler 912. As baler 912 moves across a field
(e.g., as towed by vehicle 910 via connection 910a) and encounters a windrow or other
arrangement of material (not shown), pick-up assembly 916 may gather the material
and move it up and into housing 914 for processing. As a result of this processing,
as described in greater detail below, bale 918 may be formed and may be ejected from
the rear of baler 912.
[0036] In various embodiments, baler 912 (or vehicle 910) may include one or more computing
devices, such as controller 934. Various alternative locations for controller 934
are depicted in Fig. 9A, including locations on vehicle 910 and baler 912. It will
be understood that one or more controllers 934 may be employed and that controller
934 may be mounted at various locations on vehicle 910, baler 912, or elsewhere. Controller
934 may be a hardware, software, or hardware and software computing device, and may
be configured to execute various computational and control functionality with respect
to baler 912 (or vehicle 910). As such, controller 934 may be in electronic or other
communication with various components and devices of baler 912 (or vehicle 910). For
example, controller 934 within baler 912 may be in electronic communication with various
actuators, sensors, and other devices within (or outside of) baler 912. Controller
934 may communicate with various other components (including other controllers) in
various known ways, including wirelessly. The baler 912 and related embodiments thereto
are further described in
U.S. Publication Ser. No. 2015/0208586, the disclosure of which is hereby incorporated by reference.
[0037] Referring now also to Fig. 9B, various internal components of an example configuration
of baler 912 are depicted. It will be understood that various other configurations
may also be possible. Pick-up assembly 916, for example, may include rotary tine pick-up
922 for gathering crop material from windrow (not shown). Material gathered by rotary
tine pick-up 922 may be routed to feed auger 924, which may further direct the material
toward baling chamber 938 for compaction into a baler.
[0038] Baling chamber 938, which is depicted with upper panel 938a in place, may be a chamber
of generally rectangular cross section extending axially along baler 912 in a generally
front-to-back direction. Chamber 938 may be configured in various ways to receive
material gathered by pick-up assembly 916, hold the material for compaction, then
release the resulting bale from the back (or other portion) of baler 912 (e.g., as
depicted for bale 918, in Fig. 9A).
[0039] Baling chamber 938 may be bounded on one or more sides (e.g., to the right and left,
from the perspective of the forward direction of baler 912) by tension panels 952,
which may be movable in order to control various aspects of a baling operation. For
example, various actuators (not shown) may be mounted to baler 912 and one or more
of tension panels 952 such that the actuators may cause tension panels 952 to vary
the cross-sectional area of baling chamber 938. In certain embodiments, for example,
hydraulic pistons (not shown) may be configured to pivot tension panels 952 into (or
out of) baling chamber 938, in order to decrease (or increase) the cross-sectional
area of chamber 938 and thereby increase (or decrease) the force required to push
a given amount of compacted crop material through chamber 938 (e.g., the pressure
required for plunger 954 to move the bale through chamber 938). In this way, for example,
tension panels 952 may be utilized to vary the density of the resulting bale 918.
[0040] Compaction of crop material within baling chamber 938 may be driven in various ways.
For example, as depicted in the various figures, plunger 954 (not shown in Fig. 9B)
may be driven by a crank arm assembly. As depicted in Fig. 9B, power take off ("PTO")
connection shaft 926 may be configured to receive rotational power from PTO shaft
of vehicle 910 (e.g., via connection 910a, as shown in Fig. 9A). In certain embodiments,
accordingly, whenever the PTO output of vehicle 910 is engaged, PTO connection shaft
926 may be receiving rotational power from vehicle 910. (It will be understood that
various other configurations are also possible, such as configurations in which shaft
926 (or various other components of baler 912) may be selectively disengaged even
if the PTO output of vehicle 910 is engaged.)
[0041] In various embodiments, PTO connection shaft 926 may provide rotational power to
gear box 928. Through one or more internal gears (not shown in Fig. 9B), this power
may be routed through gear box 928 to crank arms 930, which may be connected to plunger
954 via connecting rod(s) 932. (Connecting rods 932 have been partially removed in
Fig. 9B, for clarity of presentation.) In this way, rotational power may be provided
from vehicle 910 to crank arms 930. Crank arms 930, accordingly, may then drive the
reciprocating motion of plunger 954, via connecting rod(s) 932, in order to compact
material within baling chamber 938 into formed bales 918. It will be understood that
various other configurations may be possible. For example, in certain embodiments,
gear box 928 may be powered by an electrical or hydraulic machine rather than by direct
mechanical power from a PTO interface.
[0042] In various embodiments, rotation of PTO connection shaft 926 (e.g., as powered by
the PTO output of vehicle 910) may additionally (or alternatively) provide rotational
power to various components of baler 912. For example, the motion of various components
of pick-up assembly 916, various tying mechanisms (not shown), pumps for hydraulic
actuation of tension panels 938 (not shown), and so on, may be driven via power connections
of various known types (e.g., chain or belt drives) to PTO connection shaft 26 or
associated components.
[0043] A twine tying arrangement (not shown) may be provided for wrapping and tying multiple
loops of twine about a completed bale. The bale tying cycle may be initiated by a
bale length sensor arrangement (not shown) including a toothed metering wheel (not
shown) mounted on a shaft (not shown) extending horizontally across and being rotatably
mounted to the top of the baling chamber 938. The metering wheel may have a toothed
periphery which extends into the baling chamber 938 and is contacted by a forming
bale so as to be rotated as the bale grows in length. The rotation of the metering
wheel is sensed and converted into a signal representing bale length, with a control
signal being sent to initiate the tying cycle when the forming bale reaches a length
corresponding to a desired bale length. An example of a twine tensioner or knotter
system is described in
U.S. Patent No. 8,617,834 to Deere & Company, the disclosure of which is hereby incorporated by reference.
[0044] As the baled crop is formed in the baler 912, certain parameters or qualities of
the crop may be measured or determined, e.g., moisture quality, baling time, bale
weight, bale length, etc. This is further described with respect to Figs. 11 and 12.
In any event, the ability to trace or track baling parameters can be useful to an
end user. Baled products, such as hay or silage, may be fed to livestock, and the
quality of the feed may be important to the diet of the livestock. To achieve this
traceability of the baled product, a tagging system may be employed for storing or
otherwise retaining the parameters or quality of the crop. For example, a higher quality
feed may be fed to certain livestock, whereas feed with lesser quality may go to a
different type of livestock (e.g., dairy cow versus a dry cow).
[0045] In the organic food industry, for example, traceability of feed quality is desired.
Many in the industry want to know where food products (such as milk) come from, what
the livestock ate while it was being raised, etc. As a result, the tagging system
may be employed in the baling process to provide this type of information to the consumer.
[0046] An example of the tagging system is shown in Fig. 10 of the present disclosure. In
this example, a bale of hay 1000 is shown formed in a rectangular shape with twine
1002 wrapped around and fastened about the crop. As described above with respect to
Figs. 9A and 9B, the hay may be picked up by the baler 100, fed through the baler
via a baling process and extruded out the rear end thereof. During the baling process
and once the bale 1000 is formed, the twine 1002 may be fastened or tied along the
length of the crop in a conventional manner. As shown, there may be one or more pieces
of twine 1002 coupled thereto.
[0047] As also shown, a first bale tag 1004 and a second bale tag 1006 may be coupled to
the twine 1002 at different locations along the length thereof. Each bale tag may
be coupled to the twine either before or after the twine is fastened to the baled
crop. Moreover, each bale tag may include a radio-frequency identification (RFID)
chip or other technology coupled thereto that provides a unique means for identifying
the tag relative to other bale tags. In other words, each bale tag may include a different
identifier (e.g., alphanumeric identifier, numeric identifier, etc.). In other embodiments,
the bale tags coupled to each baled crop may include the same identifier, but the
identifier is different compared to bale tags coupled to different baled crops. While
in Fig. 10 there are two bale tags shown coupled to the twine 1002, in at least one
other embodiment only one bale tag may be coupled to the twine 1002. Thus, there may
be one or more bale tags coupled to and associated with a baled crop.
[0048] The manner or timing in which the bale tag is coupled to the twine 1002 is non-limiting.
In one example, the bale tag may be coupled to the twine 1002 during the baling process,
e.g., after the twine 1002 is fastened to the baled crop 1000. Alternatively, the
bale tag may be coupled to the twine 1002 in advance or before the baling process.
For example, the bale tag may be coupled to the twine 1002 by the twine manufacturer.
Thus, in this example only, the supply of twine to the baler 100 may already include
bale tags coupled thereto.
[0049] As described, each bale tag may include a RFID chip and antenna for transmitting
signals to a remote location. Other technology may be incorporated in the bale tag
including, but not limited to, a visual identification such as a barcode, a quick
response (QR) code, or any other visual identifier known to the skilled artisan. In
any event, the bale tag includes a readable identifier that corresponds to the bale
tag and may be detected by a bale tag reader, as described herein. In at least one
embodiment, the bale tag is not writable. In other words, the bale tag includes a
unique identifier associated only to that bale tag that is readable by a machine or
reader, but the machine or reader cannot write data or other information to the bale
tag.
[0050] The read-only bale tag allows flexibility over other conventional means. A user may
wirelessly scan the tag via a scanning device, or scan the tag with a mobile device
(i.e., scan a barcode or QR code according to known methods). In doing so, this enables
a user to collect or associate data related to the baled crop via use of the bale
tag. This is further described with respect to Fig. 11.
[0051] Turning to Fig. 11, a control system 1100 is shown for managing a database of information
for identifying and tracking information about a baled crop formed during a baling
process. This control system 1100 may utilize wireless technology including Wi-Fi
and cloud-based technology for the collection, transfer, and tracking of information
related to the baled crop. However, in other embodiments, other communication technology
such as cellular communication may be used for the transmission and receipt of information.
Thus, the manner in which information is collected, communicated, and stored may vary
based on the type of embodiment.
[0052] In Fig. 11, the control system 1100 may include a work machine 1102 such as a tractor
or vehicle that is coupled to and pulls a harvesting machine 1106 such as a baler.
The harvesting machine or baler may include any of the features described above in
Figs. 1 and 9, or it may include any other known type of harvesting machine. Thus,
the type of harvesting machine may vary. For purposes of this embodiment, however,
the harvesting machine is described as a baler 1106. The work machine 1102 may include
its own controller 1104 for controlling the operation of the machine. Similarly, the
baler 1106 may include its own control unit 1108 for controlling operation of the
baler 1106.
[0053] The controller 1104 and control unit 1108 may each include a memory unit and processor.
The memory unit may store algorithms, software, look-up tables, etc. for aiding in
the operation of the work machine or baler. Moreover, the processor may execute instructions
stored in the memory for controlling the work machine or baler. As shown in Fig. 11,
the controller 1104 and control unit 1108 may be in electrical communication with
one another. In at least one aspect, the electrical communication between the controller
1104 and control unit is wireless via any known type of wireless technology. As such,
the controller 1104 and control unit 1108 may communicate with one another as necessary
for controlling the work machine 1102 and baler 1106.
[0054] In addition to the control unit 1108, the baler 1106 may also include a data server
1110. The data server 1110 may be in electrical communication with the control unit
1108. The server 1110 may provide a local storage unit for storing data, information,
and the like as collected by the baler 1106. As shown, the baler 1106 may include
a sensing unit 1112. The sensing unit 1112 may include a plurality of sensors or other
detection-based means for detecting or measuring data about a baled crop formed by
the baler 1106. In this embodiment, the sensing unit 1112 may include a first sensor
1114, a second sensor 1116, a third sensor 1118, and a fourth sensor 1120. In other
embodiments, the sensor unit 1112 may include any number of sensors.
[0055] The sensing unit 1112 may be mounted inside the baler, such as the baling chamber,
to measure and record data related to a baled crop 1124. In Fig. 11, the baled crop
1124 may include at least one piece of twine 1128 fastened thereto, and a bale tag
1126 is coupled to the twine 1128. The bale tag 1126 may be read by a bale tag reader
1122, as shown in Fig. 11. The bale tag reader 1122 may be a RFID reader, a barcode
reader, a QR code reader, or any other known reading device. The bale tag reader 1122
may be mounted to the baler 1106 in a location downstream from where the twine 1128
and bale tag 1126 are coupled to the baled crop 1124. In other embodiments, however,
the bale tag reader 1122 may be located upstream from where the twine 1128 and bale
tag 1126 are coupled to the baled crop 1124. In one example, the bale tag reader 1122
may read the bale tag 1126 before the bale tag 1126 is assembled to the twine 1128.
In another example, the bale tag reader 1122 may read the bale tag 1126 after the
bale tag 1126 is assembled to the twine 1128, but before the twine 1128 is tied to
the baled crop 1124. In yet a further example, the bale tag reader 1122 may read the
bale tag 1126 after the bale tag 1126 is assembled to the twine 1128 and after the
twine 1128 is tied to the baled crop 1124. Other configurations may be possible as
well.
[0056] In Fig. 11, the control unit 1108 is disposed in electrical communication with the
sensing unit 1112 and the bale tag reader 1122. In one example, the control unit 1108
may be in electrical communication with each of the plurality of sensors directly
or via a communication bus. Thus, the bale tag reader 1122 can detect or read the
unique identifier associated with the bale tag 1126 and communicate the identifier
to the control unit 1108. In addition, or alternatively, the bale tag reader 1122
may be in electrical communication with the data server 1110, and thus it may communicate
the identifier to the data server 1110. As such, at least one of the control unit
1108 or data server 1110 can store the identifier associated with the bale tag 1126.
Moreover, the control unit 1108 or data server 1110 may wirelessly communicate, e.g.,
via cloud-based technology, the identifier to a remote location such as a mobile device
1130 or remote server (not shown). This allows a user to receive the bale tag identifier
from the user's mobile device 1130.
[0057] As described, the sensor unit 1112 is capable of detecting or measuring a plurality
of different characteristics of a harvested produce and the production of the baled
crop 1124. These parameters may include, but are not limited to, a moisture content
of the harvested produce, a dry mass content of the harvested produce, bale weight,
and bale length, width or diameter. Other information may characterize the suitability
of the harvested produce as fodder including protein content, acid detergent fiber
(ADF), neutral detergent fiber (NDF). Other information may include a global positioning
sensor (GPS) position at a start or end of the baling or wrapping process, date, and
time. A sensor may also detect machine status such as start of baling process, end
of baling process, start of wrapping process, end of wrapping process, ejection of
baled crop, etc. Another GPS may detect an area of collected harvested produce, position
of a completed bale, position of bale storage after the baling process, a type of
harvested produce, compressed density, silage-making agents used (type, quantity,
etc.), use of cutting blades (none, one set, two blade sets, etc.) for determining
size of the stems of material inside the bale, a carrier material used for forming
(e.g., mesh), a carrier material used for wrapping (e.g., twine, film), manufacturer
of carrier material (e.g., twine manufacturer), shelf life (UV resistance of film,
quality of harvested produce for baling process), and any other type of characteristic
that may be measured or detected by the sensor unit 1112.
[0058] If twine is used as the carrier material and fastened to the bale during the baling
process, the twine may come supplied in a roll and inserted into the harvesting machine
or baler. As such, information about the twine may be detected and communicated to
the control unit 1108, data server 1110, or other database (not shown). Information
may include an identification number associated with the twine, the type of consumable
material, date of manufacture of the twine, compatible machine (e.g., John Deere C440R),
roll size (e.g., diameter, length, width, weight), recommended application (e.g.,
six layers with 50% overlap), serial number of the roll, and position or location
of the twine. The twine may be supplied with a visual identifier such as a barcode
or QR code, or include an integrated RFID transponder similar to the bale tag. The
bale tag reader 1122 or other reading device on the baler may be able to detect the
identifier or otherwise scan and transmit the information about the twine to the control
unit 1108, server 1110, etc.
[0059] In one embodiment, the harvesting machine or baler 100 may perform a baling process.
During the baling process, hay or other material may be collected by the baler and
formed into a bale as described above with reference to Figs. 1 and 9A-B. As the bale
is formed, the sensor unit 1112 can detect or measure various characteristics about
the bale. In the baling chamber, for example, a moisture sensor can measure an electrical
resistance or capacitance of the bale for detecting its moisture content. Another
sensor can measure the length of the bale. Each characteristic or parameter that is
measured may be done so by one or more sensors of the sensor unit 1112. Each measurement
may be communicated to the control unit 1108 for recording. The control unit 1108
may communicate the detected measurement to the data server 1110 or other database
for storage. The measurements may be stored locally via the data server 1110 or wirelessly
communicated via a mobile device 1130 to a remote location over the cloud-based technology.
[0060] When each bale is formed, the control unit 1108 may assign an identification number
to the bale. This identification number is unique to all other bales formed. In addition,
the identification number assigned to each bale may be different from the identification
associated with the one or more bale tags coupled to the bale via the twine. Thus,
as the bale is formed and the control unit 1108 associated an identification number
to the bale, the bale tag reader 1122 reads the one or more bale tags 1126 and communicates
the tag identification number to the control unit 1108 or data server 1110. Moreover,
the sensor unit 1112 or each sensor may communicate measurements and other data detected
to the control unit 1108. The control unit 1108 can therefore associate the measurements
with the bale identification number and bale tag identification number. Alternatively
or in addition, the control unit 1108 may communicate the measurements from the sensing
unit 1112 or each sensor, the bale identification number, and the bale tag identification
number (when communicated via the bale tag reader 1122) to the data server 1110 or
database.
[0061] Referring to Fig. 12 of this disclosure, a data matrix 1200 or spreadsheet is illustrated.
As shown, the data collected or recorded may be stored in an organized format so that
it may be retrieved at a later time. For example, a user of a mobile device 1130 may
access the data wirelessly via Wi-Fi, cloud-based technology or any other known communication
means by accessing the server 1110 or database where the information is stored. In
this manner, the data associated with any baled crop may be tracked from a remote
location at any given time.
[0062] As shown in Fig. 12, the data matrix 1200 may include a plurality of columns and
rows of characteristics or parameters related to a formed bale. The plurality of columns
may include the bale identification number, a first bale tag identification number,
a second bale tag identification number, a first measured parameter, a second measured
parameter, a third measured parameter, and a fourth measured parameter. There may
be any number of columns and rows in the data matrix based on the number of bales
formed, number of tags coupled to each bale, and the number of measurements taken
or parameters stored for each bale. As shown, each bale may include one or more tags
and therefore one or more tag identification numbers may be associated with any given
bale. Even when more than one bale tag is coupled to a bale, the control unit 1108
is able to correlate the bale identification number and measured parameters associated
with the bale to the one or more bale tag identification numbers.
[0063] In the event information about the twine is collected by the control unit 1108, the
data matrix 1200 may include one or more parameters corresponding to information about
the roll of twine. When a carrier material other than twine is used, data may be collected
for the carrier material and associated with the formed bale according to the methods
described herein.
[0064] While the previously described embodiments refer to wireless communication, other
embodiments of this disclosure may utilize the communication of the different parameters
and identification numbers via any known wireless or wired communication. In addition,
data storage may be achieved locally by the memory in the control unit 1108 or the
data server 1110. Alternatively, the control unit 1108 may communicate the information
to the controller 1104 and stored on the work machine 1102. Further, information may
be stored in a separate hard drive, database or server on the baler 1106. Moreover,
information may be stored remotely on a server, database, or other storage means.
[0065] A user may access the data and information via a mobile device 1130 utilizing any
known means such as a dedicated application on the mobile device 1130. Moreover, a
remote computer may access the data and information according to any known means.
The data and information may be stored for any length of time.
